Similarly as in the 1DOF example, we have compared our results with an approach using neural networks in the actor-critic scheme. The number of parameters needed is 123001 for a deep neural network DDPG [1]} and 3941 for a neural network used in [2]}. In contrast, the symbolic V-function depicted in Figure REF , found by the SVI-SNGP method, has only 77 parameters.
